I have been using a Nemesis NC210P for four years. I had it modified at the factory for dual 110/240 volt.
I have been very happy with this amp. I have been playing for over 30 years and have owned Ampeg, Fender, Acoustic, Sunn, Peavey, SWR. I bought this amp cold, without trying it, based solely on the reviews in Bass Player, Harmony Central, and BGRA. I was living in the Middle East at the time and didn't have access to a well equiped music store. Not my preferred way to go, but I was joining a band and needed something on very quick notice. The criteria I had in mind was:
-minimum 200 watts
-I always liked the sound of 2-10's
-light weight. I lost interest in moving Ampeg 2-15's, Acoustic 301's, 4'10's etc.
-Useful features (line out, pre in/out, tuner out, DI out, speaker on/off)
- under $1,000
I have been very pleased with this amp. I like the voicing of it and it satisfied my search criteria.
I run it flat. The only tone control I change is the parametric EQ dependant on the room I'm playing in. I run a Sadowsky Outboard preamp between my basses and the amp and the combination sounds great. When the amp is pushed, I get a really nice growl from it. In fact, it sounds better than the SABDDI that I bought last year and sold last month.
I currently play in a three piece with a guitarist using a Soldano head and two Marshall 1-12 bottoms. The drummer is loud. There was only one gig where I could have pushed more air and the front of house didn't offer enough bottom ooommmfffff. Next time we do that room, I'll rent a bigger system. Other than that, the amp is fine. I have used it for a number of quiet jazz gigs as well.
In the four years I have owned the amp, I have never really needed anything bigger. I'm not a big fan of loud stage volume, despite playing predominantly classic rock/blues. The amp did shut down on me twice three years ago. Both times were outdoor gigs in the desert and the outside temperature was very high. I was running the amp quite loud and the thermal protection system kicked in. Both times, the amp started up again just fine, as stated in the owners manual. No damage done.
I had a stand built for the amp that also doubles as an equipment case. The stand is 6 inches high at the back, and 8 inches high at the front, giving it some tilt so it isn't firing into the back of my legs.
This amp is made by Eden. They built good products. It's made right beside the Eden production lines. It's lighter than similar Eden combos. The amp, amp stand, mic stand, trolly and gig bag fit comfortably in the trunk of my 320i. I can put everything on my trolly for one trip into a gig. I can get a great sound out of it and enough volume for small gigs, enough stage volume for bigger gigs when running through a front of house.
The only valid reason I would have for changing it is to satisfy GAS.
